[Q] bluetooth & wifi not turned on !! help me - Galaxy S 4 Q&A, Help & Troubleshooting

Hello. Bluetooth and wifi notr work on my galaxy s4! I tried to reflash with odin the latest rom available (XXUBMGA ITV) but nothing. I tried the solution in various forums but have not found anything. IMHO is definitely a software problem because before you restart the phone everything worked perfectly. Someone can help me?:crying:

Did you do a data factory reset after flashing the stock rom?

Then it may probably be a hardware problem and you should take it in for repair.

I have already sent in for service the phone for the same reason and after 3 days I was resubmitted. Samsung assistance do not tell me what was done!!

There is not much more you can do than reflashing the stock rom and resetting the phone, turn it in again for repair because the problems with BT and wifi are still there bro. They may have to replace the motherboard.

It is possible that the failure is determined by the coupling with a Polar heart rate monitor? because it is the last thing I did. However, until you restart the phone bluetooth and wifi worked perfectly, it is possible that a hardware problem?

You could try uncoupling it, reboot and see if it works well then. Is this heart monitor coupled continiously (by bluetooth?)

Take it in for repair bro, it should not be your problem and it should be fixed correctly. If it is repaired and you pick up the phone bring a bluetooth headset with you to check wether the bluetooth issue is resolved. I never had any issues with wifi and bluetooth.

I checked and I am certain that Samsung did not change the form of wifi nor bluetooth (mac adress are identical), then the solution is software. I have not tried to reflash a rom older. could solve? there is some secret code to reactivate the bluetooth driver?Thanks

I deleted the data of the service Google Services Framework and did a reboot and bluetooth and wifi started working and turned on. at the second reboot did not work yet is not a hardware problem..but what can it be?

@DexterJack:
Have you found a solution?
I had the same problem starting on August 15th with Bluetooth suddenly stopping and forcing another app to stop.
(I'm on stock rom i9505XXUBMGA).
Since then the phone is trying to switch Bluetooth on/off every 30 sec. (10 sec. "trying on" (dark green in the notification menu), 30 sec. off (grey)).
WLAN is also not working anymore. WLAN connects for ca. 10-30 seconds and then switches itself off.
LTE works.
A few times over a period of several hours the device reboots randomly (but without fixing the problem afterwards).
I have removed the battery for 8 hours, but that and all other things I tried did not help.
Then, after using LTE for ca. an hour, I saw that Bluetooth switched on!
I could then normally activate WLAN and everything worked like before (I have the S4 since end of April).
WLAN and also (already paired) Bluetooth connections worked fine again.
This was the situation since yesterday (10 days of heavy use without any issue).
Yesterday I opened the Bluetooth settings menu to pair new loudspeakers.
Within seconds the Bluetooth and WLAN problem reappeared.
Since 24h the same problem is back.
Could it be related to firmware/radio UBMGA?
(I had no issues with UBMF8 and the other stock firmwares before)

same here ;(
have u already tried to flash stock with repartition?
are u both on pure stocks? (red somwhere custom binary/system mark in bootloader may cause such problems)

@bofff:
No, I have not flashed any (stock/custom) ROM yet and no repartitioning.
I read in another forum that flashing different ROMs didn't help.
This user tried three different ROMs, two different kernels, full wipe etc. (I haven't read anything about repartitioning).
He finally flashed it back to stock and sent it in for repair.
Samsung didn't find anything, but Bluetooth and WLAN worked again.
One day later the same problem happened again.
A new factory reset didn't help.

my s4 is still repaired by Samsung..

Possible Fix
I had the same problem (also on MGA) and managed to solve it. The trick was to flash an older firmware. But it didn't work after the first flash.
In combination with the WiFi and Bluetooth problem i had a notification telling me that a program tried to do something unsafe and that i had to reboot my phone to fix.
Here is what i did :
1) Complete wipe of the phone
2) Flash older firmware with odin (I used this one LUX-I9505XXUBMEA)
3) factory reset (at this point still no WiFi and Bt)
4) flash same firmware again.
After this my phone worked normal again.
But I have a second problem that came right after flashing this MGA rom. It seems like my battery is broken. Sometimes my phone switches of with still 30% left. I need to plug him in to the wall to boot the phone.
Not sure if this has anything to do with flashing MGA firmware, but at least my Bluetooth and WiFi are working fine now.

YET another Possible GPS issue fix for CM6..Tested!

Hey guys, so I am just like some of you who are the victims of the GPS issue when flashing CM6 nightly. At some point for me GPS failed to lock me in quickly, and it's somewhat broken, because it usually took about 2-3 minutes to lock under clear sky, and about 4-5 minutes inside of my apartment. Before the issue, it locks like instantly. Anyway, did some research and ran into a post that really helped me cleared up the issue and here's how you do it.
Things you need:
1. A rooted stock Froyo 2.2 ROM, yes there's no way around it because you will need to dial some "##" code, and CM6 dialer doesn't support some of it as I know of.
2. Your MSL code. The quickest way is to get this app from market (thanks JFree for sharing).

[/QUOTE]
OK ready?
Code:
1. Nandroid backup your current CM6 (will need to restore later)
2. Boot to recovery
3. Wipe data, cache, Dalvik
4. Flash the rooted stock rom
5. do a wipe data, cache, dalvik one more time to be sure after flash.
6. Let it boot up and the next step is VERY important
7. Launch phone dialer and dial ##GPSCLRX#
8. It will ask you for your MSL, feed it.
9. Upon hitting OK, your phone will just say reboot in 10 secs, let it reboot.
10. Once rebooted, launch maps and your GPS should lock almost instantly.
11. If it worked, then boot into recovery.
12. Wipe data,cache,dalvik
13. Restore your previous CM6
14. Now try to launch maps again and you should expect same result as in step 10.
15. If NOT, then reboot and do a wipe.
NOTE: the way I understand GPSCLRX is that it somehow clear some settings internally within the radio and/or via your account provisioning with Sprint. I think the long lock time is caused by something got stuck in the process.
NOTE: For me after step #13, it worked right away, even inside of my apartment, without me having to do a wipe.
Try it out and please post your results.
Source/reference: http://community.sprint.com/baw/thread/37566 --> although it was meant for Hero but it worked for Evo apparently.
EDIT: I did several reboot after the fix and same result of instant lock. I will continue to test for several days to see if this is a permanent fix or not.
I fixed mine on accident doing everything EXCEPT the dialing GPS thing.
I just flashed to sense, my GPS locked on, flashed back to CM6 and I was good (wiping data and cache TWICE between every rom flash). If you don't have your MSL you can try what I did first and maybe save some trouble.
This worked for me. Amazing. Thank you, sir.

Not a problem, just spreading the knowledge. This app was made by a forum member btw.
worked for me
Worked for me, dear lord thank you. I wonder if one of the nightly builds corrupted this?
Thanks OP. It worked just like you posted.
Yep took my phone on a road trip to Vegas this labor weekend and GPS is locking instantly even when I was in MGM grand hotel room. I used the google nav the entire time while driving and having it plugged to charger, there was no hickups whatsoever. This Evo is rocking solid.
The ##GPSCLRX# command worked perfectly for me as well. I didn't bother with all the extra wipes (other than one before the new ROM flash). I'm convinced that all these WIPE EVERYTHING TWICE THEN WIPE IT AGAIN steps in a lot of guides are basically rain dancing.
worked like a charm..thanks!
I was hopeful after getting linked to this thread, but my GPS still locks extremely slow after following all the steps, I didn't get a quick lock on #10, rebooting and wiping again didn't help either.
Just posting to balance out the raucous "It works!" statements.

Did you try other methods other than this? If yes and still doesn't work then your phone might have an issue.

No, I haven't, actually. Other than flashing stock -> Sprint Nav. (Which doesn't lock any faster)
Since topics sink so fast, would you mind pointing me in a direction to look? Thanks much.

Bro it always did worked for me almost 99.99% cases, and secondly i have tried doing all this well in advance. I tried almost 3-4 such softwares(simialar to drivermax/drp.su)
to check as to any update for my device driver, but nothing works. . !
Any other solution is more than welcome.

Yes brother its a genuine copy of Windows 8.1 [x64] OS.

Brother, I faced this issue on both the CM-11 ( currently installed on my phone) and when I was initially on MiUi v6.4.2.0[KHIMICB] , the issue was on that ROM too.
Doesn't understand why such happens frequently with me.
Highly pissed off.
Regards.
I have miui and not cm. This problem occured about a month after using the phone, so I got suspicions that the phone itself was responsible for this. Particularly I used to "dirty" flash each miui developer rom in the top of the previous, and just do a wipe cache and wipe dalvik cache before. So I decided to move to a miui stable version with clean install. Did a full wipe, cleaned everything and installed rom. After that everything worked just fine with every windows pc and laptop I've tried.

I understand this brother. Though i never developed any ROM or such thing myself, but i have been tinkering with almost every device i ever got my hands laid on.
Its in my habit to do a full clean swipe of everything be it system wipe, cache, dalvik cache basically everything which a developer says to do before installing a new ROM on the device.
I have been doing it from the start, but still got this issue.
I did a clean install [twice] of MiUi ROM[Stable] but still this issue came in like every 10-20 days. So , recently i have switched to a custom ROM , CM-11 as i mentioned.
For now i am using an alternate to transfer content between the two devices, and waiting for someone from the developers end to help me out.
Lets see when do i get a stable solution for this never-ending issue.

for Developer Option Enable
MIUI 5
1. Go To "Settings > About Phone > Android version."
2. Tap "Android version" until developer mode appears.
MIUI 6
1. Go To "Settings > About Phone > MIUI version."
2. Tap "MIUI version" until developer mode appears.
after that, you can check your device is attached to your window via adb command
To enable USB try *#*#717717#*#* and it'll not connect as regular USB but visible under debugging mode.
type the same command on your phone it will [I]disable[/I] USB and once disabled - now it will appear in your my computer and visible as USB drive.

Lag and Performance issues.

Hello, I have an old NOTE 4, ive had it since release date but ive started to get issues, its only happened in the past month, ill explain every single thing that is happening below.
1. When switching from apps sometimes it will take so long to open the app and during this time i literally cannot do anything, cannot open the app drawer to force close apps, cannot slide from the top to see the notification bar, after a 30seconds it will lock the phone screen (The time i have the timeout on i suppose) and then i cannot even open the lock screen nothing literally works, maybe after a minute or two it will finally let me. Sometimes a battery pull is needed.
2. When typing it will lag and do the same thing above with the freezing, and even during these processes once the screen goes black (sometimes i can still see the notification bar) the phone will completely restart itself on its own.
3. Just other general slow downs.
Here are the steps I have done to try and solve it (still no luck)
1. Wipe Cache and Dalvik Cache through TWRP.
2. Uninstalled apps and cleared out files
3. Installed an antivirus software and run tests.
4. Formatted SD Card (Removed it as well)
5. Completely formatted the whole phone (Every single bit of data (selected all options in TWRP except SD Card) so it says no OS has been installed.
6. Installed the latest stock firmware through samsung kies.
All of the issues are still happening, whether i root it or not, it will do the same. Im out of ideas and have no idea what to do. Its becoming so annoying having to constantly pull out the battery and what not.
Hmm I don't know what to say as you have already done a complete wipe! But I don't understand how you flashed the firmware through Kies though! Doesn't than need an already working phone with a ROM already installed? Don't know, have not used it for long time.
Just try to flash the stock firmware via Odin once, see if that makes any difference, after a complete wipe of course. And please don't use any anti virus, that's not needed at all.

Well it never used to do this so I can't see it being touchwiz, I just think the phone is nackered
Sounds like something is seriously off with your phone and that it needs to be repaired.

All of the issues are still happening, whether i root it or not, it will do the same. Im out of ideas and have no idea what to do. Its becoming so annoying having to constantly pull out the battery and what not.

Did your baseband somehow change. That will cause super serious lag issues and it will not get any better until you reflash modem. Also maybe try a different kernel

[SOLVED] Wi-Fi no longer works with Airplane mode enabled?

I was able to use Wi-Fi with Airplane mode in the past. But now suddenly it doesn't let me?
I toggle airplane mode, then enable wifi in settings. Then get the toast notification "In Airplane mode"
Any fixes?

You sure about being able to use Wifi with airplane mode enabled previously?

Yes, I have screenshots with it working too. I find this quite weird.
Edit: Going to downgrade my purenexus version and see if the issues persist

Yeah it actually works for me, just checked. I'm also on Pure Nexus but the 0803 build (not the most recent 0821 build).

It's worth a try if it's something you need to work.

Well, I got Google play working. But for some reason wifi does not want to toggle while on airplane mode anymore.
Do you perhaps know of a way to force toggle WiFi?
Another edit: I found a solution! Under /data/data/com.android.settings/databases/settings.db, airplane_mode_radios in the global part. The wifi toggle got disabled. And since I only wiped System, Dalvik cache, and other cache. And reflashed vendor and not the data partition. The random change was not fixed. That took well over 5 hours to fix. A experience I learned from at least!

Am on LP 5.1 here on G4 H81010o, and 4.4.2 CloudyG3 on G2, both can use WiFi in airplane mode.

Reviving this thread with the solution, which is really a simple solution
My issue is that I was re-dirty flashing my PureNexus ROM. And I restored contacts data. And that data ended up being the issue. I cleared the data for the app, but it persisted. So I did a quick data wipe - I uninstalled almost all of my apps because I'm cutting down on apps. - after writing down important contacts. And to my pleasure. It worked! I re-entered the contacts and did a more recent backup of contacts and restored that backup just to test. And everything is working fine.
PS: I didn't try a data wipe first because I was going somewhere with poor signal and no wi-fi and ran out of time when troubleshooting.
TLDR: Always try a clean flash if all else fails.
Edit: I found that my settings.db data was corrupted as well from a f-sync disabled caused data loss. And that is what caused the Airplane mode not working with Wi-Fi issue. Always try a clean flash and backup important data every so often!

Does anyone have any ideas on what's going on and how I can resolve it? I've tried a whack of stuff like turning off location sharing, removing apps that might sync that I don't use, changing sync settings, etc. I can't figure out what the problem is and it's driving me crazy!
Thanks!
To be sure it's not the hardware I would completely fastboot flash latest stock image with complete wiping internal too.
Use it for a day without magisk modules and a bunch of apps to see if the draining still exist. And if you should use a magnetic charger adapter, don't use it, it's a deep sleep brake and drainer.

Clean flash, may it helps, otherwise it might be a hardware issue.

I flash stock. Deep sleep not woking.
Edit : recovery eror red : rec error on uevent how to fix?
Thx you support . :fingers-crossed:
Which twrp version ? Older one ? Then ignore the error.
May you try to figure out what prevents deep sleep for you. Wakelock detector app for example. Did you really completely clean flash stock without any additions, no root, no twrp, no apps ? to check if deep sleep works on pure stock.

Go for latest official twrp, cosmic is only for treble necessary.
For drain, I don't know, check wakelocks, provide a log and hope someone can help you with it, clean USB port, format internal storage and reflash stock. I'm sry.

I will trying.
Report form you complete. Thx mate support. Have a nice day.??
I flash ROM stock via fastboot clean all.
No recovery , no root. Pure stock.
Deep sleep not work? ???
Did you fix this issue?? I am facing the same problem.
I have had this problem for a year now. My phone is affected by the 700000.ssusb wakelock which prevents Deep Sleep. I did try rooting my phone and installed Lineage 16 with Canting kernel which used to occasionally solve this issue but not during all charging cycles. Many Mi A1 users are affected by the CPU stuck at 652 MHz frequency issue which leads me to believe that it might be due to a hardware issue.

Didn't people conclude that this issue was related to hardware liquid damage ? (more specifically, I remember seeing people saying this was a result of letting water inside the charging port).

I'm not sure that was conclusive. I have read posts in other threads saying that changing the ports made no improvements in battery life. I've also read posts saying that the wakelock problem disappeared on its own within few weeks.
